Regions: Banff Yoho Kootenay.

Recent snow has refreshed the skiing in most areas. The biggest concern is fresh windslabs as you transition into the alpine.

Weather Forecast

Cold air will continue through Wednesday and then start to warm up on Thursday. Valley bottom temps on Wednesday in Lake Louise will be -15. Flurries forecast for Thursday, but little accumulation. Ridgetop winds will pick up Wed afternoon into the mod to strong range.

Snowpack Summary

15-25 cm low density storm snow creating small windslabs in alpine and some treeline locations. Storm snow overrides a variety of surfaces including sun crusts, faceted snow and isolated areas of surface hoar. The Dec 2 crust/facet layer is down 70-120 cm and is producing variable shears.

Avalanche Summary

One storm slab (size 2) observed in Flow Lake area in Kootenay on Tuesday. Ski hills reported several small natural and explosive triggered windslabs.

Confidence

Avalanche Problems

Wind Slabs

Fresh windslabs can be expected in alpine lee areas.

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2

Persistent Slabs

This problem represents both the Dec. 2nd crust/ facet layer (treeline and below) and the late December facet layer. We have not seen much recent activity on this layer however we continue to monitor it carefully.

  • If triggered the wind slabs may step down to deeper layers resulting in large avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely

Expected Size: 2 - 3
